I think the documentation is clear here though:
"a complex-valued expression exp".

This means the type that is accepted is "_Complex type", which can be prompted
from type.

Maybe we should add that scalar types can be prompted to _Complex types just to
make it fully clear what is allowed. Let me take a stab at that.
